How Were These Companies Selected?

Companies were considered when an official website connected the business with family ownership or family operation and published relevant service coverage for Milwaukee, Greater Milwaukee, or nearby Southeast Wisconsin communities. The evaluation also considered the breadth of waterproofing, drainage, crack-repair, wall-repair, pump, excavation, or structural services.

This is not a review-score ranking, price comparison, or claim that family ownership guarantees better work. The sponsor receives first placement. The other companies represent different local service models, from independent Milwaukee contractors to a family-run dealer in a larger waterproofing network.

Ownership descriptions can change. Some websites use “family-owned” as a marketing description without publishing current legal ownership records. Homeowners should therefore treat family ownership as one comparison factor, not a substitute for checking the diagnosis, written scope, insurance, permits, warranty, and payment terms.

The company was founded by Donald M. McCoy, and Daniel J. McCoy is the verified current president and principal contact. An official video-gallery page describes the company as a family-owned business.

What Should You Ask a Family-Owned Contractor?

Use this checklist during each consultation:

  • Is the company currently family-owned, family-operated, or both?
  • Who performs the inspection, prepares the proposal, and supervises the work?
  • Will employees, subcontractors, or a combination complete the project?
  • What caused the water entry, cracking, settlement, or wall movement?
  • Which repair options were considered, and why was one recommended?
  • Are products proprietary, dealer-network products, or available from multiple suppliers?
  • Who handles engineering, permits, excavation, cleanup, and restoration?
  • What does the written warranty cover, exclude, and require from the homeowner?
  • Is the warranty transferable, and are service fees or maintenance visits required?
  • How will change orders and unexpected site conditions be documented?

A family-owned structure may affect communication or decision-making, but the contract still matters most. Compare the written diagnosis and scope rather than relying on an ownership label alone.

Frequently Asked QuestionsIs McCoy Contractors Currently Family-Owned?

The company’s official video gallery uses the phrase “family owned business.” Donald M. McCoy is the verified founder, and Daniel J. McCoy is the current president and principal contact. Present legal ownership was not independently confirmed, so the status should be verified before publication.

Does Family Ownership Guarantee Better Basement Waterproofing?

No. Ownership structure does not guarantee workmanship, price, communication, or results. Evaluate the inspection, proposed method, written scope, insurance, permits, warranty, and contract terms.

Should I Compare a Family Business With a National Chain?

Yes. Comparing different business models can reveal differences in products, repair methods, warranties, maintenance requirements, scheduling, and who controls project decisions.

What Should Be Included in a Waterproofing Estimate?

The estimate should identify the observed problem, proposed solution, materials, labor, preparation, cleanup, exclusions, payment schedule, warranty terms, and responsibility for permits or engineering.

Can a Family-Owned Company Belong to a National Dealer Network?

Yes. A local company can be family-owned while selling or installing products through a larger dealer network. Ask which company provides the labor, warranty, maintenance, and future service.
